山东省高青地区地热资源环境效益研究

山东省淄博市高青地区地热资源为层状砂岩类裂隙-孔隙型地热,地热概念模型显示,地热源主要来自地壳深处及上地幔的传导热,热储层主要为较大厚度的新近纪馆陶组和古近纪东营组砂层,高青断裂为导水断裂,热储盖层为巨厚的第四系和新近系明化镇组粘性土层。评估高青县地热资源量为1.74×1019J,地热流体可开采总量为6.57×106m3/a,以地热供暖方式有效利用地热资源,节煤量可达25 879.71 t/a,环境效益显著。

Land Use Change During 1960-2000 Period and its Eco-environmental Effects in the Middle and Upper Reaches of the Yangtze River： a Case Study in Yiliang County, Yunnan, China

Land use/land cover change (LUCC) is a focus of the research of global environmental changes.The middle and upper reaches of the Yangtze River,which are the most ecologically fragile mountainous area in China as well as one of the areas in China with most notable LUCC, have been on the Chinese Government‘s list of priority areas for ecological restoration. This paper is to reveal the trend of LUCC and the ecological degradation arising from it, and to provide a basis for the future sustainable use of land resources in the region based on a detailed analysis of Yiliang County. Based on the county‘s land use/cover maps in 1960, 1980 and 2000 drawn with the aid of aerial photograph interpretation, field investigation and GIS based spatial-temporal data analysis, LUCC during 1960-2000 period and the ecological degradation arising from it were analyzed. Using the Markv model, the paper brings out a forecast of what the county‘s LUCC would be like if the county‘s current land use continues, as well as the reasons and countermeasures for restoring degraded ecosystems.
